Non-planar corrections in ABJM theory from quantum M2 branes
Journal of High Energy PhysicsThe quantization of semiclassical strings in AdS spacetimes yields predictions for the strong-coupling behaviour of the scaling dimensions of the corresponding operators in the planar limit of the dual gauge theory.

Recursive Relations for the S‐matrix of Liouville Theory
Fortschritte der Physik, Volume 73, Issue 11, November 2025.Abstract The relation between the vertex operators of the in and out fields in Liouville theory is analyzed. This is used to derive equations for the S‐matrix, from which a recursive relation for the normal symbol of the S‐matrix for discrete center‐of‐mass momenta is obtained.

Symmetry, Integrability and Geometry: Methods and Applications, 2005 The complex WKB-Maslov method is used to consider an approach to the semiclassical integrability of the multidimensional Gross-Pitaevskii equation with an external field and nonlocal nonlinearity previously developed by the authors.

Nonlinear Fokker-Planck Equation in the Model of Asset Returns
Symmetry, Integrability and Geometry: Methods and Applications, 2008 The Fokker-Planck equation with diffusion coefficient quadratic in space variable, linear drift coefficient, and nonlocal nonlinearity term is considered in the framework of a model of analysis of asset returns at financial markets.

On non-planar ABJM anomalous dimensions from M2 branes in AdS4 × S 7/ℤ k
Journal of High Energy PhysicsPlanar parts of conformal dimensions of primary operators in U k (N) × U −k (N) ABJM theory are controlled by integrability. Strong coupling asymptotics of planar dimensions of operators with large spins can be found from the energy of semiclassical ...

Quantum scattering with semiclassical asymptotic motion
, 2018 Conventional scattering theory is incomplete in that it does not adequately describe the behaviour of the wave function at macroscopic distances from the scattering reaction volume. In scattering experiments particles are incident from sources at macroscopic distance and measured at macroscopic distance from the microscopic reaction volume.

Semiclassical asymptotics, gauge fields, and quantum chaos
Journal of Functional Analysis, 1989 A gauge field is given by a connection on a principal bundle P → M. We consider the semiclassical behavior of a family of Schrödinger operators associated with a gauge field, in the limit as . We relate the spectral theory of such operators to behavior of the Hamiltonian flow on the natural phase space associated to a gauge field, examining in ...

Transverse Evolution Operator for the Gross-Pitaevskii Equation in Semiclassical Approximation
Symmetry, Integrability and Geometry: Methods and Applications, 2005 The Gross-Pitaevskii equation with a local cubic nonlinearity that describes a many-dimensional system in an external field is considered in the framework of the complex WKB-Maslov method.

LAD Asymptotics under Conditional Heteroskedasticity with Possibly Infinite Error Densities [PDF]
Least absolute deviations (LAD) estimation of linear time-series models is considered under conditional heteroskedasticity and serial correlation. The limit theory of the LAD estimator is obtained without assuming the finite density condition for the ...
